ping does not natively make those 'deductions', be it is easy to write a wrapper that does that for you.

Re: IP Chains Rules
I had the same thing with bezeqint on ISDN. Everything went well until they installed a POP proxy (MiraPoint). I know that Internet Gold uses the same equipment and have the same problems with few of their customers. Fortunately, I have overcome this issue and can advise you to do one of the following: 1. Call inetgold and ask their support personell to tell you the IP address of the exact mail server you need to connect to. 2. Play with your MTU/MRU settings - after a while bezeqint blocked direct access to the POP servers by forwarding them to the proxy using their firewalls, and changing my MTU to 1152 (or was it 716?) did the trick. Your MTU is probably 1500 or 1499 if you didn't change it, so you can have a go with this.

Re: 2.4.4
I have run the 2.4.4 kernel and runs flawlessly.
As for what you stated on XFS, true, but it you don't use XFS,
then you wouldn't need any of the XFS tools, as with many other kernel
features.
For example: How many people install ipchains, or ipvsadm on kernel
2.2? Still, the kernel manages to do very well without them. These user
tools are needed for control of these subsystems and when they don't
exist, the kernel has a default behavior (such as, being able to mount XFS
partitions).

This is a kernel. What can it depend on?
Assuming you have a proper compiler, binutils, modutils, etc. for 2.4,
there should be no problem using/building this spesific version.
Maybe you'll lack some user-space programs to exploit certain features,
but this is not exactly a dependency.
[Or am I missing anything?]
> Does anybody know whether a Cooker kernel can beinstalled under the
> standard version?
I suppose you'll want to compile it yourself. Either download the -source
rpm and build it, or (probably a better option) download the source rpm,
extract it, and run 'rpm -bp path/to/kernel.spec' . This will extract the
kernel and apply all of the patches.
The atvantage here is that by tweaking the spec file you can try to add or
remove certain patches ("try": because some patches depend on other
patches, and may need to be changed in order to be applied properly after
another patch was removed. Still, it is worth a try).

Wow. Zillion things...
One example:
In one of the last Cookers (I don't know if the latest too), I saw
an XFS supporting kernel, plus a special XFS fsck and other user-
level programs for XFS. If you take this kernel and put it under the
standard 8.0, you don't have these programs.
Let me re-ask my question:
I didn't ask if the Cooker's kernel depends on specific parts of
Cooker; It DOES depend. What I asked, was - what parts exactly?

There may be a different compiler, glibc, etc., in Cooker vs. 8.0.
